The present paper deals with the problem of large displacement frictionless contact between a rigid obstacle and an elastic body. In Klarbring a formulation of this problem which makes use of a distance function G is given, and in Björkman the related computational scheme is presented. We give in this introduction a summary of these works, which shows the central position in the computational scheme of the function G, its gradient ΔG and its Hessian Δ2G. In the next section we present a particular distance function that is useful when, in the computational realization, the rigid obstacle is a CAD surface with continuous curvature. As an example of such a surface, we briefly present the conceptual ideas of Ferguson bicubic spline surfaces. Then a search algorithm needed for determination of the value of G during iterations is given. Finally, we present some test examples.

Black faculty members navigating the tenure process in higher educational settings, especially historically Black colleges or universities (HBCU), quickly learn within their careers that the job at hand requires a lot of time, energy, and persistence. Extant literature highlights the difficulties Black scholars face in such settings; however, it is vital to shedding light on the positive aspects that occur daily. This chapter highlights a component of collaboration that is often under shadowed in the educational setting, the faculty–graduate student partnership. Given the lack of resources and infrastructural elements that often plague HBCUs, in comparison to other institutions, faculty members inadvertently and unconsciously establish partnerships with advanced undergraduate and graduate students. Without the assistance of young, emerging scholars, tenure-earning faculty may struggle with maintaining a healthy work–life balance. Moreover, forging strong partnerships with mentees aids in faculty and student development alike. This narrative encompasses the views, experiences, and perceptions of a young, tenure-earning faculty member. Additionally, past and present graduate students provide insight on perceptions of faculty–student interactions and their subsequent development as scholars, researchers, and clinicians.

This paper aims to consider the impact of contractual and normative governance mechanisms on recommendation intent in a context of healthcare and professional lighting where repeat business from a customer is absent. The authors suggest both contractual and normative governance can create recommendation intent, but only when sufficient customer value is created.

The authors draw on a combination of survey and archival data from the supplier and customer in the medical equipment and advanced (business) lighting systems industries. The authors analyze the data using seemingly unrelated regression and mediation tests.

Contracts and relational norms can increase customer recommendation intent, but only when the supplier creates customer value.

The paper’s findings suggest that customers of business solutions are more likely to recommend their supplier when contracts are relatively detailed and when buyers and suppliers attempt to craft strong relational norms, despite service solutions being delivered during a relatively short time span.

The extant research on business solutions has focused on extended relationships between exchange partners with a high likelihood of repeated transactions. The authors demonstrate how to govern relationships in a solutions context where the likelihood of repeat business from the same customer is low using contractual and normative governance.

This conceptual work synthesizes the experiences of Black men who are collegiate athletes and introduces new theoretical considerations on the formation of their leadership identities in predominantly white institutions. This scholarship focuses on historical understandings of how race and gender influenced the creation of the current Black man in collegiate identity. This work expands on Du Bois' (1903) concept of double consciousness, Fanon's (1952) views on Blackness, and Bertrand Jones and colleagues' culturally responsive leadership learning model (2016). Collectively, the three frameworks highlight the significance of leadership in the development of Black men who are student-athletes. The conclusion includes implications and recommendations for future research as we work to support and develop Black men beyond their athletic identity.

The purpose of the paper is to describe and analyse the evolution of the supplier base of a buying firm and the reasons behind these changes.

The paper is based on a case study of the changes over 52 years in a sub-set of the supplier base of a firm manufacturing fork-lifts.

The study shows that some relationships feature substantial longevity. However, the duration of one-third of the total relationships is shorter than five years. There was considerable variation over time in the dynamics of the supplier base in terms of entries and exits of suppliers. Owing to this variation, research findings and conclusions in short-term studies are heavily dependent on the specific conditions at the time of the study. Finally, no less than one-fourth of the terminated supplier relationships were reactivated later.

The study was designed in a time when purchasing was considered entirely from the perspective of the buying firm. Further studies, therefore, must increasingly emphasise the role of suppliers and the interaction in the buyer–supplier relationships, as well as the embeddedness in networks.

The findings of the study are unique in two ways. First, they are based on systematic observations over more than 50 years. Second, the study involves the purchases of 11 components representing different technical and economic features. The (few) previous studies are based on much shorter time periods and involves fewer suppliers/components. Moreover, the findings regarding re-activation of terminated relationships represent unique contributions.
